| Description of the problem | In this initial incident, i was traveling on a curvy road at posted speed limit of 30mph. My vehicle suddenly slowed, as if i was applying the brakes, which i was not, and my steering was compromised. In addition the vsc indicator and symbol flashed on my dashed and beeped. The road was dry. This has occurred 10+ times since. I have brought it to my mechanic, without turning the engine off after the occurrence so that he could "read" the computer but there is no evidence available. We have brought it to the toyota dealer. They "rebooted" the sensors and said it should be fine. It has continued to happen, on the freeway going uphill at 55 mph, going downhill at 60 mph and has been close to causing a rear end collision each time. |
